Is this 100% free??
Thank you so much bro, Shalom brother your the best instructor and teacher, i now know how to code in Kotlin.
Just a comment of appreciation. This video its 5 hours long, has subtitles (no automatic, writted subtitles), its well recorded, the concepts are well explained and the audio its really good.
This channel really takes his time to make this content with a good intention and tries to create something with the best quality possible. Im really gratefull for their job and I really appreciate that they take their time to make this thing really good.
For them, probably it would be easier/cheaper to not make the subtitles and upload more videos faster, but they put the effort and the time. They reslly care. Im deaf, I need the subtitles and for me its a gift to have the possibility for enjoy this content and learn it. I know that in the past they didnt make subtitles but they improved with time.
Thank you amigos code for your content. I wish you the best! Have a good day! Lots love!
THANK YOU NELSON! Happy to see you spreading the Kotlin word.
One of my favorite teacher have a Kotlin course, that's great !! ... thank you very much !!
wasted too much time between sections trying to sell stuff Course was lacking in content because he was too busy trying to make money
Springboot kotlin projects that demonstrate interoperability would be nice. Working with core spring libraries like security, MongoDB. How to add kotlin to java projects. And how to leverage existing Java code solutions when needed.
Awesome lessons, ty so much!
Very explicit as always. Thanks so much. Please can you do a SpringBoot-Kotlin tutorial? Pleaseee
Thanks so much for this!
i was waiting for this course.. thank you so much sir
Wonderful video. I love your contents, build products is being involving along the process. ❤❤
وعليكم السلام ورحمة الله وبركاته..... مرحباً أخي, حياكم الله و بارك الله فيكم و لكم.....
Excellent tutorial thank you
Thank you so much Amigoscode
Brilliant! can't wait! 🙂
Thank you very much for this good tutorial

This tutorial is great in every corner, I hope the full course will release soon, it's been 10 months
This is it now !! i was just chilling and banggg !! Kotlin .
I can't wait for this!!
Thank you very much.
Would be awesome to have more Kotlin videos
i literally start my work with kotlin next week, from java. thank you amigos!
Im learning Kotlin language now.... My theme is to built an API ...what are topics should I cover.... could you please guide me?
@@kammillabalaji3102 google just a few step away
I am hitting the like button, the moment I hear Assalamaalikum! Have learned a lot from your videos. Thank you brother!
Waalaikumsalam, brother. thanks for the great Kotlin lesson.
Make video on collections, exception handling and coroutines in Kotlin PLEASE!!!!
Jazakallah khairan brother
wooow very excited, looking forward to attend this course. salam alaikum bro
thanks for the tutorial bro
finally. Kotlin for android development is amazing!!!
Thanks for nice video
Thanks Nelson
Day 1 - 26:15
good I need this
Great work Nelson..eagerly waiting since a long time
Full course🎉
I like that you used bigger font 😅… great for my eyes and easy to read
Kotlin & Spring boot & security please!
Hello, for new Spring Boot projects, the Entity class, should have the id as an optional and filled by JPA automatically or there is another aproach ?
It depends on your requirements of your application whether you need Id or not.
Good luck ❤
God with you.
cool video)
Awsome i will start watching this night i just hope it is about creating java web apps and java api project. I am not into mobile dev at all.
you look nice guy i watch 30 mins of your video i don't understand a thing , even i did take and finish course cs50 .
About time!!!!
will you provide Jetpack Compose tutorial too?
It's really good, just one thing to make it even better is remove the "join the waitlist" from beginning of every chapter, it's a bit distracting, I know you worked hard for it and it should be here, but before every chapter is a bit overkill, include it after, say, every 4-5 chapter and we are good to go, promotes your product and also give viewers 15-20 sec of relax timing. win-win for both.
Lol, go make a 5-hour video and teach us. Better Still, go buy a book. Why are you complaining if it's absolutely free?
@@cephasmee6456 It's called a feedback
Yeah, welcome to Kotlin!
Wow! Finally
WAALAIKUMSALAM YAA AKHIIII
Do you have a multi module course?
"Nyan Progress Bar" is the best )))
Assalamu aleikum bro, I'm looking forward to watch this course
qattansiz brat)
Mashallah homie, hope this video does well!
It's a great beginner course but soon we want an intermediate course cause its a fun a handy language like a thanos glove
:)
i think the intermediate one will be paid
Hi, I would like to ask on which platform you make this course, on MacOS or Windows?
he uses macos, but since intellij idea is the same on macos / windows / linux, it really does not matter at all.
just that i need to start kotlin
Would you be switching to Kotlin for your upcoming Spring Boot tutorials?
How do i get quick help with errors in my coding as am learning?
then what do you recommend to learn at first instead of Javascript? I wanted to learn it as my first language, but I guess I have to change my mind right?
I would be appreciate if you answer me
Learn kotlin if you're new
name of the function can be double key word?
19:15 I don't perceive any issues with this theme as a COBOL developer 😄
Let's gooo, recommanded langage for native Android app code!
Recommended but java is on its way striking for its position. Look at its amazing look of java21 boom. Okay it may not be the number one (recommended) language for Android development but its code is getting precise and more expressive each update. For the love of Java, lets wait for the premiere.
Wa Alaykum Salam brother., I have completed my bachelors in business administration but somehow I got interest in full stack develop... And I joined the course for six months now i understand some topics and some topics are not understanding and this makes me worrying I donno how to improve give me some suggestions or ideas to overcome it and able being a best software developer.
Hi Nelson! I love your courses but I don't understand why the font size is so big. It makes less comfortable to read the code
wa alaikum assalam amigo
وعلیکم السلام! Now I have to learn Kotlin.
💯
Is it An Android development course or a Kotlin course using spring boot
how would i input °C = (°F - 32) × 5/9?
what state management is used in Android I come from background of Flutter where we use sate management like Provider, River Pod, Bolc etc.
Just know that kotlin is a language not a framework like flutter
I can't but could you please premiere it tomorrow 🤪
waiting
at the end of every section, you have this end screen with incorrectly spelled experience as "EXPIRIENCE"
Assalamu Aleykum, bro we need Java OOP and Hibernate🙂
I wanted to learn kotlin, do I need to learn Java?
Why is 4.5 rounded down?
## Kotlin
23.12.28 - 1:16:55
💜
Do we need to learn all the documentation in Kotlin?
For starters no but as you progress you need to go through documentation.
Catch me in the next one. 👍🙂

Olikum assalam
Please, not for beginners, but for experienced Java programmers thinking about switching languages...
"don't you use these" me happy with light theme: 👁👄👁
You didn't explain the `as` keyword at the end
4:06:00 Oh man, Z charecter is not the best to choose now a days :D
LESGOOOOOO
وعليكم السلام
It's been 10 months, what happened?
fun main(){
var a = "Abhishek"
var b = "Karan"
var c = "Amana"
//val name2 = String("Suraj".toCharArray())
println(a==b)
println(b==c)
println(a.length)
println(b.length)
println(c.length)
println(b.length == c.length)
println(b === c)
}
this code gives me wrong answer as per you teach in lecture, please provide me proper explatiion
Being locked in to an IDE wich isn't completely open source nor free is BAD!
👇 Number of people who never used do..while loops in their life
It’s very useful to replace recursion or when u work with linked lists in some programming languages such as python
कोटलिन हिंदी भाषा में 😊
See durgesh for it
Who is Jamila 😂
Update the microservices course! Or give me my money back!
videos that have who include "beginners" word in the tittle, let me tell you something, they just work to make a "hello world" program, they are wasting time, they work for nothing
no kotlin only java 🎉
Wowowkwo
are you british?
